Necrosis: Programmed Cell Death?
Necrosis is widely considered a “premature” death of cells and tissues. However, it is possible that the process can in fact occur as a type of programmed cell death, similarly to apoptosis. …Recent data indicate that, in contrast to necrosis caused by very extreme conditions, there are many examples when this form of cell death may be a normal physiological and regulated...

Dentate Gyrus
The Dentate Gyrus is a part of the hippocampus formation essential in forming new memories. The region is one of the few in the adult brain that has high rates of neurogenesis, the creation of neurons. Offspring of female mice that exercise frequently tend to have a significantly higher quantity of cells in their dentate gyrus, suggesting that aerobic exercise stimulates neurogenesis in the...

Enzyme corrects more than 1 million faults in DNA... →
sciencebriefs: Scientists from the Medical Research Council Institute of Genetics and Molecular Medicine at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA. The mistake is the inclusion of individual bits of RNA within the DNA sequence, which the researchers found occurs more than a million times in each cell as it divides. The...
